121

Mobile Abdomen: Dorsal decubitus, lateral position not a common bedside projection…useful for:

demonstrating a possible abdominal aortic aneurysm or as an alternative to the lateral decubitus position if the yet cannot be moved.

122

Trauma & Mobile Cervical spine: Always perform the ________ projection first.

horizontal beam lateral

123

Trauma & Mobile Cervical spine: The attending physician or radiologist must:

review this image before performing other projections.

124

Trauma & Mobile Cervical spine: Swimmer's poistion: Do not move the pt's arms without permission from:

the attending physician and review of the lateral projection.

125

Trauma & Mobile Cervical spine: Swimmer's Lateral: Position: Start:

Supine, usually on backboard and in a c-collar. Have pt depress shoulder closest to tube as much as possible. Do not push on pt's shoulder.

126

Trauma & Mobile Cervical spine: Swimmer's: Instruct pt to raise arm opposite:

the tube over his/her head. Assist pt as needed, but do not force or move the limb too quickly. Ensure pt is looking straight ahead without any rotation of head or neck.

127

Trauma & Mobile Cervical spine: Swimmer's: CR

horizontal and perpendicular centered to C7-T1. A 5 degree caudal angle may be required if pt cannot depress shoulder opposite IR.

128

Trauma & Mobile Cervical spine: AP Axial

DO NOT perform this projection until the attending physician has reviewed the lateral projection. If pt is on a backboard, either on a stretcher or an X-ray table, gently and slowly lift the backboard and place the IR in position under the pt's head.

129

Optional AP Axial C1-C2 region when open mouth projection not possible.

Fuch's. Angle CR cephalad 35-40 degrees or as needed to align CR parallel to a line from symphysis of mandible to base of skull.

130

Trauma & Mobile Cervical spine: AP axial oblique:

Do not use grid IR because the compound CR angle results in grid cut-off.

131

Trauma & Mobile Cervical spine: AP axial oblique: IR position:

under the immobilization device, centered at level of C4 and the adjacent mastoid process. CR is directed 45 degrees lateromedially. When a double angle is used, angle 15-20 degrees cephalic.

132

Trauma & Mobile Cervical spine: Where does the CR enter on an AP axial oblique?

slightly lateral to MSP at the level of the thyroid cartilage and passing through C4.

133

Trauma & Mobile Cervical spine: Oblique method 2:

Angle CR 45 degrees medial and 15 degrees cephalad and center to C4. Place IR at a 45 degree angle just below table height on an adjustable stand or stool.

134

Trauma and Moble AP Pelvis: grid placement

Ensure the grid is horizontal and parallel to the pt's MCP to minimize distortion and rotation.

135

Trauma and Moble AP Pelvis: What is often performed following a diagnosis of a pelvic fracture?

An emergency cystogram. Have the necessary equipment and contrast media readily available.

136

Trauma and Moble AP Pelvis: Up to 50% of pelvic fractures are:

fatal as a result of vascular damage and shock. The mortality risk increases with the energy of the force and the health of the victim.

137

Pelvic fractures have a high incidence of:

internal hemorrhage. Alert the attending physician immediately if abdomen becomes distended and firm.

138

Hemorrhagic shock is common with:

pelvic and abdominal injuries. Reassess pt's level of consciousness repeatedly while performing radiographic examinations. Do no attempt to internally rotate limbs for true AP projection of proximal femurs on this projection.

139

Venipuncture defined as:

the percutaneous puncture of a vein for withdraw of blood or injection of a solute such as contrast media for urographic procedures.

140

Bolus injection:

provides a rapid introduction of the contrast agent int o the vascular system.

141

The rate of bolus injection is controlled by:

Gauge of the needle or connecting tubing.
Amount of contrast being injected.
Viscosity of contrast agent.
Stability of the vein.
Force applied by the individual performing the injection.

142

Drip infusion:

Permits a larger amount of contrast agent to be introduced over a a longer period of time.

143

Universal precautions are in line to:

protect you from wide variety of pathogens that could cause disease.

144

Universal precautions are mandated by:

law (OSHA) to report any exposure. If exposed when to using universal precautions, insurance does not cover.

145

Best defenses against exposure:

Know your pathogens
Hand washing
Gloves
Goggles
Mask
Immunization

146

Hand washing is the most important precaution but most often:

ignored.

147

Hand hygiene refers to:

decontamination of the hands using soap and water (for a minimum of 30-60 seconds) an antiseptic hand wash, or an alcohol-based hand rub (about 15 seconds)

148

Latex gloves do have some:

permeability

149

Nitryl and vinyl gloves are:

not as flexible and pliable, tend to rip

150

Remember to bandage any open wounds you have have to prevent:

entrance of bacteria and that GLOVES TO NOT PREVENT NEEDLE STICKS!
